Hi, I've been getting occasional (every hour or two) BSOD with 0x00000024 stop errors, which are apparently related to Ntfs.sys going bonkers. I've run chkdsk /f/r which came out clean, installed windows 7 upgrade on top of the one I'm running now, hoping it would fix any dodgy windows sys files, and tried dropping my OC back to box-stock settings, all to no avail. Bar formatting and reinstalling, which I'm loathe to do, is there anything else anyone could suggest I try?
